PART 3 - EXECUTION
3.01 Inspection
A. Prior to installation of the expansion joint profile, the installer will visit the site and notify the proper authority in writing of any conditions (done under other sections) that might be detrimental to the installation or performance of the expansion joint. Coordinate the installation with related work.
3.02 Preparation of Surfaces of Block Out Recess in Deck
- Construct the block-out recess and joint opening to the dimensions shown in the manufacturer’s literature. The width of the joint opening should comply with the dimension shown in the temperature/adjustment table on the contract plans. The anticipated movement should be within the movement limits of the seal size selected for use.
3.03 Installation
A. DD-Edge Rails -
- The edge rails are made from ASTM 6061-T6-aluminum material, which enables the heat welding of various configurations at directional changes and transitions, as mentioned above. These changes in plane, irregularities around columns, wall-to-floor, or up-and-over conditions, such as stairs or curbs are a common occurrence. Thermo-plastic material lends itself very well to solving these difficult to seal conditions. Assure proper 1/8” spacing between rails for expansion.
- Factory-made directional changes and transitions may be made at EMS’s fabrication plant, according to drawings and dimensions provided by the field contractor. However, with minimal training, field crewmen will adapt quickly to successful splices.
B. Side Flashing Sheet
1. The side flashing sheets are optional. If required for specific projects the sheets are provided in rolls of 12” wide 1/8” thick PVC sheeting. PVC material will allow heat welding at all joints for continuous waterproofing at all transitions, corners, upturns, etc. The flashing sheet may be inserted into the top channel or into the side extruded reglet located on the vertical leg of the aluminum edge rail.
2. If required, flashing sheets will be “sandwiched” between two layers of the deck waterproofing system. The flashing materials must be PVC-based material to ensure adhesion with deck waterproofing materials. Flashing sheets have a short-term temperature resistance (350F - 400F.) suitable for integration with the hot applied, deck waterproofing membrane systems.
C. Stainless Steel Cover Angles
1. The formed stainless steel cover angles comply with ASTM A167, Type 304 with mill finish. They are secured to extrusion with stainless steel machine screws, 6” on center, which are seated into the countersunk seats in the stainless steel angles. These formed angle covers are removable to allow for expansion joint gland replacement. At locations where cover plates are required over top of the DD-series gland, a specially fabricated stainless steel cover plate to can be made to extend across the sealing gland and rest on the top of the opposite side cover angle. Sizing of the plate is dependant on loading and width of the joint opening.
D. Factory Fabrication Of Transitions and Temperature Adjustment
1. In addition to factory heat welded splices, EMS’s fabrication plant we will also fabricate the aluminum edge rails to match the field conditions.
2. At the time of installation, the engineer of record will be consulted for the temperature adjustment table. This will determine the joint opening “setting” at that given deck temperature. Preset the distance between the aluminum rail extrusions prior to anchoring the rails into place with the use of spacers. Keep in mind that the opening may be wider or narrower by the next day. Adjustments must be made to keep in sync with the deck temperature.
E. Surface Condition
1. Joint surfaces to receive system will be sound, smooth, straight, parallel, and level from side to side.
F. Installation
1. Inspection: Manufacturer's technician will be on site at commencement of installation for inspection of substrate preparation and demonstration of installation procedures. Bids must include a specific line item for manufacturer’s technical service and will be considered incomplete and subject to disqualification if excluded. Technical service is defined as the paid, contracted service of a manufacturer’s representative or factory technician.
2. The following is a general summary of installation requirements. In all cases the manufacturer’s standard written instructions or specific instructions of the manufacturer’s technician are to be followed.
G. Anchorage
1. Use epoxy anchoring devices and fasteners for securing expansion joint cover assemblies or concrete expansion anchors. It is the contractor’s option to purchase fasteners from manufacturer. Fasteners will be 3/8” diameter x 4” long anchor, carbon-steel grade II, zinc-chromate yellow finish, UNC 16, threaded end- to-end, with nuts of the same material.
H. Size-up
1. Perform all cutting and fitting required for installation of expansion joint covers. Install joint cover assemblies in true alignment and proper relationship to expansion joints and adjoining finished surfaces measured from established lines and levels. Take into consideration movement table from engineer.
2. Allow adequate free movement for thermal expansion and contraction of metal to avoid buckling. Securely attach in place with all required accessories. Locate anchors at recommended intervals, not less than three inches from each end.
3. Maintain continuity of expansion joint cover assemblies with end joints held to a minimum and metal members aligned with metal guide pins
I. Seal Placement
1. Integrate flashing sheets with deck waterproofing system materials according to waterproofing manufacturer’s instructions. Install seals in continuous lengths to eliminate leakage opportunities. All transitions and terminations will be factory-welded wherever possible according to field measurements and drawings on centerline provided by the contractor. Site welding, when needed, will be carried out after suitable instruction by the expansion joint manufacturer and/or their representative.
J. Site Cleanup
1. Dispose of all waste materials from the site. Seal will be cleaned of all foreign matter as recommended by the seal manufacturer
3.05 Field Quality Control
A.Work that does not conform to the specified requirements will be corrected and/or replaced as directed by the manufacturer and engineer.
B.Manufacturer/installer will supply guaranty/warranty to the owner authority, as required.
